Category V Portworx is one of the most well-known and respected cylinder-head porting specialists in the ecotec world, but it doesn’t stop there.

Owner, Josh Billheimer, started as an enthusiast in 2006 after purchasing his first ecotec-powered vehicle. Through the years of ownership, he experienced what brings these engines to life, but also their shortcomings, which drives his passion even more.

With more than 15 years of experience in the industry, 10 years as a Honda Master-Technician, it was only obvious to bring a business to the industry that provides quality and knowledge unlike any other —  welcome to Category V Portworx.

Cat 5 is a full service shop with unmatched customer service and attention to detail. This also shines through with the release of new products that keep owners on the road. Whether it be a hard-to-diagnose electrical issue or bringing back a once unavailable product, Category V Portworx puts the passion first.
